چکیده مقاله :

سابقه و هدف: ویروس آنفولانزا یکی از مهمترین عوامل مرگ و میر طیور بر اثر بیماریهای تنفسی است که سالیانه خسارات زیادی را به صنعت پرورش طیور در سراسردنیا وارد می‌کند.پروتین هماگلوتینین(HA) از عوامل اصلی در بیماری‌زایی این ویروس است لذا هدف از پژوهش حاضر کلون کردن و بیان این ژن در سلول Sf9 با استفاده از باکولوویروس می‌باشد.مواد و روشها: بعد از جداسازی ژنوم ویروس آنفولانزا H9N2، ژنHA توسط پرایمرهای اختصاصی با روشهایRT-PCR و PCR تکثیر و با کمک وکتورpFastBac Dual به بکمید منتقل گردید. بکمید نوترکیب واجد ژن HA به سلول میزبانDH10Bac انتقال داده شد. با ترانسفکت کردن سلولSf9 با بکمید نوترکیب، چگونگی بیان و میزان بیان پروتین نوترکیب با روشهای SDS-PAGE، western blotting و بردفورد بررسی شد.یافتهها: پروتین حاصل از بکمید نوترکیب با استفاده ازSDS PAGE بررسی و خلوص آن تائید شد. غلظت پروتین نوترکیب در محلول رویی سلولهایSf9 آلوده به ویروس نوترکیب µg/ml 138 تخمین و توسطwestern blotting تائید شد.نتیجهگیری: در تحقیق حاضر ژن HA بر روی وکتورPfastBacDual با موفقیت کلون شد و بعد از انتقال بر روی بکمید و ترانسفکت به سلولSf9 بیان مناسبی از ژن در محلول رویی سلولهایSf9 بدست آمد. با انجام آزمایشهای حیوانی، این پروتین میتواند به عنوان واکسن نوترکیب بر علیه آنفولانزا H9N2 مورد استفاده قرار گیرد.

چکیده انگلیسی:

Background & Objectives: Influenza virus is one of the most important causes of death due to    respiratory diseases in poultry, which causes a lot of damage to the poultry industry worldwide every year. Hemagglutinin (HA) protein is one of the main factors in the pathogenesis of this      virus. The aim of this research is cloning and expression of this gene in Sf9 cell using baculovirus.Materials & Methods: After isolating of the H9N2 influenza virus genome, the HA gene was       amplified by specific primers by RT-PCR and PCR methods and transferred to Bakmid using pFastBac Dual vector. The recombinant HA gene was transferred to the DH10Bac host cell. By transfecting Sf9 cells with recombinant bacmid, the expression of recombinant protein was         examined by SDS-PAGE, western blotting and Bradford methods.Results: The protein obtained from recombinant Bakmid was evaluated using SDS PAGE and its purity was confirmed. The concentration of recombinant protein in the supernatant of Sf9 cells infected with recombinant virus was estimated to be 138µg / ml and confirmed by western        blotting.Conclusion: In the present study, the HA gene was successfully cloned on the PfastBacDual      vector. With animal experiments, this protein could be used as a recombinant vaccine candida against influenza H9N2 virus.
